[PyQt] pyqtdeployed app crashes on launch

[bootch at nc.rr.com]

Your latest error doesn't seem to be a failure to import, rather something else (that I don't recall seeing.)

Just guessing that bootstrap_....  is part of pyqtdeploy, you could read the code, which is open source.
Or if it is part of Python, you could also read that code.
Or wait for someone else to respond.

Remember that when you execute your app, it is totally divorced from the installed Python.
Any errors are coming from the Python interpreter and modules that pyqtdeploy compiled into your app bundle.

You might try rebuilding from scratch.  Although a lot of time passes, you can read a book.
